the when is July to October 2000, the how is with a set of plans to take down members of the justice league that were then stolen by ra's al ghul, the why is in order to be prepared for members of the justice league turning evil.

happy to help, if you want to see an adapted retelling of the story you can watch the animated movie "justice league doom" which features a larger roster of villains working together instead of ra's working alone with the league

Personally, this version looks better. It's more believable Ra's al Ghoul did this, on his own (Well, with his always at-the-ready ninja clan) as part of a bigger scheme, than Vandal Savage one day grouping bunch of villains together, on a whim to rule the world.

his computer got hacked and the league of assassins use batman's contingency plans to take out the justice league. the book is called JLA Tower of Babel. superman gets beaten with a special red kryptonite, green lantern with temporary blindness and flash with a vibration bullet that sent in into a super seizure

every time it doesnt work its just plotshielding(like flash not speedblitzing his enemies,or superman forgetting that he is the strongest being on the planet,or batman not understanding obvious clues that every tom dick and jerry have already pieced together)

also while it always warns him about danger it might be that he just isnt fast enough to react to it,not to mention some of his villains have a way to get past spidey sense

Fair enough, he made his costume and his web-shooters, but aside from that the best thing he's done with his intelligence is sometimes figure out the bad guys' plot if it's science-related.

Scientific genius, maybe, but Batman is much more knowledgeable in a much wider variety of fields.

Plus, Batman ALSO has plans to take out every superhero if they go rogue, so that renders that point moot.

Sure, in a straight fight Spiderman would beat Batman (come on, the guy can dodge bullets- though somehow not always punches, no idea how that is meant to work) but as always, with prep time, Bats wins.

1.batmans "plans" have always been reliant on plot induced stupidity(seriously,kryptonite bullets for a man who fights kryptonite using villains at daily basis? a vibrating bullet for flash in hopes that he would try vibrate through it and not just dodge it???)

2.the fact that spiderman has a plan to take down beings like hulk and thor pretty much already tells us he is as good as batman with prep time.

3-as for intelligence feats(outside of his plans to take down every single hero he knows) i got
Understands Norman Osbourne's research when he is still only attending high school. Norman is impressed.
* Graduates with the "Science Award".
* Understands Otto Octavius' fusion experiment and sees the flaws immediately, while Otto who has spent his a long time on the experiment overlooked his mistakes. It should be noted by looking at Otto's work, he is likely one of the most brilliant scientists in the world.
* Curt Connors, Peter's physics professor, describes him as brilliant.
* Uses metal thrown by Ock as a counter-weight and directs it back at him.
* Fakes unconsciousness at Harry Osbourne's mansion (when delivered by Ock) to find out what is going on.
* Uses his wit to defeat Sandman by using water
* Uses his wit to defeat Venom by using sonics

also everytime spidey sense doesnt work againts punches its just plot

reality spiderman is one of the h2h combatants in marvel universe thanks to the spidey sense.it should also be noted that richard reed(a guy who built a weapon strong enough to take down galactus,who is one of the most strongest beings in marvel universe) commented that peter is almost as smart as he is

I dont really like the death battles mainly because they seem kinda one sided ever since they let Link beat Cloud. That would have been understandable but they gave Link almost every single piece of his gear including his triforce meanwhile Cloud has his starting gear. Plus Link doesnt have the super speed to stab Cloud in the middle of his Omnislash no where did they mention that
